[参考译文] AM62A7：启用 CSI-2 传感器

另一个问题
按照相同的指南构建了内核、使用加载到 SD 卡上  

sudo destdir=/media/$USER/rootfs2 make linux_install

ov5647.ko 未自动加载、  
已尝试  
root@am62axx-EVM：/usr/lib/modules/6.12.35-g72f48d59b8f0-dirty/kernel/drivers/media/i2c、insmod ov5647.ko
并得到了这些误差

[166.121794] ov5647：未知符号 v4l2_async_unregister_subdev (err –2)
[ 166.128746] ov5647：未知符号__v4l2_async_register_subdev (err –2)
[ 166.135553] ov5647：未知符号 v4l2_fwnode_Endpoint_parse (err –2)
insmod：错误：无法在模块中插入模块 ov5647.ko：未知符号

在 uEnv.txt 中添加叠加层后
 启动时加载传感器内核模块、但收到这些错误消息
[ 7.416799] virtio_rpmsg_bus virtio1：创建通道 rpmsg_chrdev 地址 0xd
[ 7.431059] ov5647 4-0036：写入 SENSOR_OE_ENABLE_REGS 错误

[7.437580] ov5647 4-0036：带有驱动程序 ov5647 的探测器失败、错误为–121
[7.443694] Remoteproc remoteproc2：远程处理器 78000000.r5f 现已连接

文档非常分散。 需要查看许多问题的论坛、不管怎样、这个问题已经解决、必须在 dtso 中进行一些更改、之后驱动程序加载就可以了、
我还面临一些其他问题、将创建新主题。  

尊敬的 Farrukh：

1.按执行步骤 4  CONFIG_VIDEO_ =y    然后尝试  sudo destdir=/media/$USER/rootfs2 make linux_install。  

ov5647.ko 将自动加载。

2.将步骤 6 修改为  

dtb-$(CONFIG_arch_K3)+= 。 dtbo 


如有任何其他疑问、请联系。

尊敬的 Farrukh：

默认情况下、 ov5647 目录不在 opt/imaging 下、您必须生成它。 为此、请参阅以下主题

首先、我从论坛上的另一个线程复制了该目录 、并 在 执行时更新了 tiovx_sensor_module 和 gsttiovxisp
GST-CHECK-1.0 tiovxisp
我们都会得到这些错误

谢谢
已 在 Ubuntu 计算机上启动服务器、IP 为 3.33
gst-launch-1.0 udpsrc port=5000 caps=“application/x-rtp、media=(string)video、clock-rate=(int)90000、encoding-name=(string)h264、payload=(int)96“！ rtph264depay！ 汤底鱼！ 视频转换！ autovideosink sync=false
还将 HDMI 显示屏连接到 开发套件、 以前曾尝试过类似的错误、  

这肯定是 DCC 槽的一些兼容性问题、  
我复制了 DCC 箱以获得 2592x1944 分辨率
尝试了完全相同的 Ctrl-v 步长和更新的分辨率、并尝试以该分辨率进行流式传输、帧速率降至 10fps、  
视频现在正在成功流式传输,但它看起来黑,我只能看到指向相机的光,休息所有黑色。
但流媒体正在运行、数据按预期在 UDP 上传输。  
下面是我下载 DCC 文件的另一个线程、 关于：SK-AM62A-LP：对大于 1920x1080 的源视频使用 H.264 编码器
但当我为相同的分辨率生成自己时、会出现相同的错误。

尊敬的 Farrukh：

此外、请检查 gstreamer 流水线的 DCC 文件路径是否正确
